Oled panel for lighting device and method of manufacturing the same

A method of manufacturing a lighting device, the method comprising:

• disposing an auxiliary wiring pattern forming material on a substrate;
• forming an auxiliary wiring pattern by etching the auxiliary wiring pattern forming material to leave auxiliary wiring lines;
• disposing a first electrode on the substrate where the auxiliary wiring pattern is disposed, by a coating method;
• planarizing an upper surface of the first electrode;
• disposing a passivation layer on the first electrode to overlap an area of the auxiliary wiring pattern;
• disposing a light emission structure on the first electrode;
• and
• disposing a second electrode on the light emission structure.

A lighting device including an array area and a pad area, the device comprising:

• a substrate;
• a plurality of auxiliary wiring pattern on the substrate, the plurality of auxiliary wiring patterns spaced apart from each other;
• a first electrode on at least one of the plurality of auxiliary wiring patterns;
• a passivation layer on at least one of the plurality of the auxiliary wiring patterns, the passivation layer including a plurality of portions spaced apart from each other;
• and
• a light emission structure on the first electrode in the array area.
